摘要: This work presents the higher order modulation schemes for standardised trichromatic light- emitting diode (TLED) and recently developed quad- chromatic LED (QLED) based colour shift keying (CSK), investigates their performance over diffuse optical wireless channels with cross-talk, insertion losses additive white Gaussian noise (AWGN). The analysis shows that uncoded unequalised QLED CSK can provide up to 288 Mbit/s data links, using standard compliant clock rate, through use of a 4096 level scheme, which is highest number levels so far been scheme. Additionally, results show scheme has better spectral power efficiencies than TLED as 256-CSK requires 4.5 dB less 64-CSK when normalised delay spread increased 0.25. both also examined without calibration, reveals 4- operate receiver having any knowledge cross- talk, makes this format an ideal signalling channel estimation cross-talk impulse response channel. analytical approximations, bit error all orders, AWGN are presented.
